In a previousyear, 59% of females aged 15 and older lived alone. A sociologist tests whether this percentage is different today by conducting a random sample of 350 females aged 15 and older and finds that 211 are living alone. Is there sufficient evidence at the =0.01 level of significance to conclude the proportion haschanged?
